Qin Zheng was Lin Sui's first ray of light on her career as a police officer. He guided her out of her ignorance and became her most trusted partner. But an accident and misunderstanding made this light suddenly go away.
As time passed over the years, Lin Sui grew up to be a unique detective, but he still couldn't let go of the answer he had given back then.
The old case was reopened, and the two had to get along day and night again.
Wariness, temptation, instinctive tacit understanding, and unconcealed care are repeatedly intertwined in each case.
The night is endless and evil lurks.
They must not only join forces to fight against the dangers in the dark, but also face the worries that have been buried for many years.
When the truth came, after several years of distance, they finally slowly returned to zero in the night walking side by side.
Purpose: Evil hides in the dark, files are recorded, and the police lights are on not only to apprehend the murderers, but also to find each other who have been separated. Identity, distance, and old misunderstandings have separated the friendship, but the same professional beliefs and the unquenched care in their hearts have allowed them to break the ice in life and death again and again. The truth not only exists at the crime scene, but also in belated honesty and reconciliation.
